Android 6.0 申請權限

如今6.0的手機越來越多，做app 就要適配6.0，6.0的需要自己去申請權限。具體可以在加載引導頁面，就去申請。

首先，sdk必須是6.0以上的。

// 申請權限的String[]

private String[] permissionArray = new String[] {Manifest.permission.CALL_PHONE,
          Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_SMS};

申請權限方法

    public void isPermissionLocal() {
        // For Android < Android M, self permissions are always granted.

        try {
            final PackageInfo info = this.getPackageManager().getPackageInfo(this.getPackageName(), 0);
            int targetSdkVersion = info.applicationInfo.targetSdkVersion;
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

                if (targetSdkVersion >= Build.VERSION_CODES.M) {
                    int permissionCheck = ContextCompat.checkSelfPermission(LoadingActivity.this,
                            Manifest.permission.ACCESS_COARSE_LOCATION);
                    // 權限未允許
                    if (permissionCheck != 0) {
                        PermissionUtils.checkPermissionArray(LoadingActivity.this, permissionArray, 2);
                    } else {
                        // 申請權限後的操作
                        getData();
                    }
                } else {
                    // targetSdkVersion < Android M, we have to use PermissionChecker
                    // 申請權限後的操作
                        getData();
                }
            } else {
                // 申請權限後的操作
                        getData();
            }
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }

    }

權限成功或失敗的回調

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
        case PermissionUtils.PERMISSION_REQUEST_CODE:
            if (PermissionUtils.verifyPermissions(grantResults)) {
                // Permission Granted
                // do you action
            } else {
                // Permission Denied
//                Toast.makeText(this, "WRITE_CONTACTS Denied", Toast.LENGTH_SHORT).show();
            }
             // 申請權限後的操作
             getData();
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

當然還有申請權限的utils

Android Studio 只要這些就行；Eclipse環境上，需要先把sdk變成6.0，就可以用了。
